Needle net rolling blind machine

Abstract

The invention discloses a needle net rolling blind machine. The needle net rolling blind machine is provided with a door and window frame groove body, an engineering plastic inner frame groove is formed in the inner wall of the door and window frame groove body, the lubricating sealing effect is achieved, and the up-and-down movement of a needle net rolling blind is facilitated. The door and window frame groove body is internally provided with the needle net rolling blind. A protecting shell is installed above the door and window frame groove body, and a rolling blind shaft is installed in theprotecting shell. The side edge of the rolling blind shaft is connected to a motor with a gearbox through a rolling blind shaft gear, and a manual turning wheel is installed on the side edge of the motor. The manual turning wheel is provided with a manual stay cord, and a clutch is installed between the manual turning wheel and the motor. A sprocket shaft is arranged below the rolling blind shaft, and the sprocket shaft is connected to a transmission mechanism through a sprocket shaft gear. The transmission mechanism is connected to the rolling blind shaft gear, and a plurality of sprocket sets are mounted on the sprocket shaft and are evenly distributed on the back face of the needle net roller blind. According to the needle net rolling blind machine, the structure is simple and practical, the problems that an existing door and window are not effective in anti-resistance measures and not attractive can be solved, and the needle net rolling blind machine has the advantages of firmnessand durability, anti-impact damage, high shock force, good anti-resistance effect, long service life and low cost. The needle net rolling blind machine can be matched with a manual rolling blind machine and an electric rolling blind machine to work, can be wound up when people at home and unwound when people not at home or at night; and attractiveness and style are achieved, and the use is convenient.

Description

Technical field: [0001] The invention relates to the field of security equipment, belongs to the fence wire mesh category, and in particular relates to a needle mesh rolling machine. Background technique: [0002] At present, there are many types of anti-theft doors and windows on the market, but the anti-blocking effect is not very satisfactory, and the cost is relatively high. Most of them adopt closed structures, which affect the lighting and affect the appearance of some commercial users. Therefore imagine designing a kind of roller net with needles, make needle mesh roller blinds, be installed on the outside of doors and windows, make it firm and durable, impact-resistant damage, and have stronger deterrent force, anti-blocking effect is good, the life-span is long, and cost is relatively low. Low. [0003] The needle mesh roller blind needs to be installed with doors and windows. In order to facilitate installation and promotion, a needle mesh roller blind machine is ...
